I would like to thank everyone who helped me with my starting problems on my 65 coupe 6 cylinder. It wound up being the fuel pump pushing out to many psi. I got it started problem know is there is a knocking noise. It is the first time starting up since I had the engine rebuilt. The noise is coming from the back of the engine towards the tranny. I can feel the knocking at the bottom back part of the oil pan. Any advice on this issue would be greatly appreciated. I tried to attach a short video of the knocking noise, not sure I did it right.
